I would like to pose a couple of questions about the power tubes in the zen amplifier and a good digital cable thats not going to break the bank . first the 6p15p-ev. somewhere I read that the large label 6p15p-ev were a better sounding tube than the small labeled ones???????? and am looking for a better digital cable than the blue jean I bought for a song , not that I dont like it belden 1694 is pretty good , is there better out there, for not so much money?????? Thanks

Well, first of all they sure do look different! As far as sound goes, I'm probably the wrong person to ask. As long as the music comes out I'm happy. I did notice quite a bit more detail than the cable that I was using before. What the old cable was, I don't know, whatever came with my Wadia Ipod dock.I will call the sound now as "Fair to partly cloudy with a chance of rain tomorrow".
